Have you happened to have seen any good papers on constructing do-it- yourself cheap, effective, portable shielding? Probably might as well ask for the moon too while I'm at it, but it's worth a shot!

Back when I was playing with that technology, there was no such thing as "cheap, effective, portable" :-) The three main applications for shielding were - FCC-grade quietness - so your neighbors don't complain about TV interference, but that's not enough to stop eavesdroppers - TEMPEST-certified equipment, which not only needs the technical capabilities correct but also the testing and paperwork, which tended to add ~$5000 per PC. - ElectroMagnetic Compatibility (EMC) testing, which uses big shielded rooms to make quiet environments for testing hardware in. The technology's pretty similar to TEMPEST-room shielding, except that you put the noisy stuff outside instead of inside, but it's the big expensive non-portable end of the product spectrum.
